Description
Package contain: 2 pieces 10A 12V-40V DC motor speed controller module This DC motor speed regulator has high efficiency, large torsion, low heat and high stable performance. Very easy to install, can be used on many projects, perfect for the speed control of fans and pumps. This stepless motor speed controller is equipped with a 10A fuse tube to protect controller from being burnt due to a short circuit. It also has reverse connection protection and voltage overvoltage protection function. Specifications: Operating Voltage: DC 12V-40V ( means 24V workable) Current Rating: 8A. Maximum current: 10A. Controlled power: 0.01-400w PWM Frequency: 13kHz PWM Speed Adjustment Range: 10%-100% Size: 60*55*28mm. Weight: 70g ★ NOTE: 1. The input is DC, NOT AC. So Do not connect directly to AC (for example: household 220V AC), otherwise it will burn out. 2. Do not reverse the positive and negative terminals of the DC power supply, otherwise this controller may be damaged.
